Please, ask Steve Ellcey sje@cup.hp.com about this.  He is most active 
developer of GCC from HP.

I think you should have figured out about HP policy first and do some 
legal paper work with FSF.  Also I thnk contribution means maintaince too.

Sorry, I don't understand question about gcc team needs optimizations.  
Many gcc developers are busy and not really interesting in Itanium 
(which is a niche platform).  But there are a lof of GCC users which are 
interesting in better Itanium GCC.  For example, as I rember about 70% 
of Gelato members would prefer to use gcc on Itanium than other 
compiler. Gcc Itanium performance is far behind Intel compiler and it 
needs to be improved.
